Synthetic Fibers Used for the Construction of Concrete Pavements

cement concrete pavements gives good durable service life and excellent applicability in heavy traffic. In plain cement concrete pavements corrosion and shrinkage cracks are the major problems. Addition of synthetic fiber to concrete mix, overcome the shrinkage and corrosion problems. In this study, discuss the effect of addition of multifilament and fibrillated polypropylene fibers on paving grade concrete mix. The concrete properties such as slump, compressive strength and flexural strength are evaluated and also compare the multifilament and fibrillated polypropylene fiber reinforced concrete mixes. The results show that the polypropylene fibrillated fiber reinforced concrete is more effective in preventing shrinkage cracks and there is no adverse effect in multifilament and fibrillated on 28 days compressive strength of concrete.
